Z86 Siliceous Earth CAS 61790‑53‑2 is purified fine‑ground natural siliceous earth filler with narrow particle‑size distribution. Applied in automotive primer and anti‑corrosion coating formulations, it builds compact barrier inside dry film, slows moisture and corrosive medium penetration. Meanwhile it boosts coating adhesion, hardness and sanding property of primer layer, optimizes construction performance, widely used in auto chassis primer and metal anti‑rust protective coatings.

Product Detail

Overview

Our Z86 Siliceous Earth CAS 61790‑53‑2 is manufactured from high‑grade natural diatomite ore via impurity removal, fine milling and multi‑stage classification. This functional mineral filler is customized for automotive primer and anti‑corrosion coating. It cooperates with anti‑rust pigments to strengthen anti‑corrosion barrier effect, improves primer sand‑ability and inter‑layer bonding force, reduces coating formula comprehensive cost for automobile metal components.

Key Features

Form compact barrier structure in coating film, retard penetration of water, oxygen and corrosive ions, upgrade anti‑corrosion performance.
Improve primer hardness, mechanical strength and excellent dry‑sandability for automobile intermediate grinding procedure.
Enhance adhesion between coating and metal substrate, promote inter‑layer adhesion of primer‑topcoat system.
Good compatibility with epoxy, acrylic, alkyd and other common anti‑corrosion resin systems.
Fine and uniform particle size, less surface defects for primer film, stable dispersion in paint slurry.
Low soluble salt and heavy‑metal content, reduce risk of premature rust spot of metal substrate.

Main Applications

Automotive chassis anti‑corrosion primer, automobile metal component primer
Epoxy anti‑corrosion primer for vehicle parts
Heavy‑duty metal anti‑rust coating for transportation equipment
Intermediate coating requiring good sanding and barrier performance
Industrial anti‑corrosion paint for metal structural parts

Usage Recommendation

Recommended dosage: 10‑30% by total weight of formula, adjust according to anti‑corrosion requirement and resin system.
Add during high‑speed dispersion stage, ensure sufficient shear force for complete de‑agglomeration.
Suggest lab evaluation on salt‑spray resistance, adhesion and sanding property before mass production.
Keep raw material dry; excessive moisture will cause pinhole and blister defects in anti‑corrosion coating.
Can be compounded with anti‑rust pigment, talcum powder and other extenders for formula optimization.

Storage & Package

Store in dry and ventilated warehouse, keep bags tightly sealed against moisture absorption.
Standard package: 25kg woven bag with inner PE liner.
